historic orchard of Dr. Maxwell near Still Pond, Maryland, more- 

 over, became the scene of experimental treatments for pear 

 Ieaf-blii;ht and scab."" August 6, Fairchild told Smith by letter, 

 " Tlie treatments were too late for a good result to be obtained 

 with the scab, and the Leaf-blight has not attacked the leaves this 

 season like it did last." Nevertheless, the results of the experi- 

 ment, he believed, would show "a good many things," and these 

 were incorporated in Galloway's ofHcial report for that year, as 

 well as made the second part of a series of three articles prepared 

 by Galloway and Fairchild, entitled, "Experiments in the Treat- 

 ment of Plant DiiSeases." 



These dealt with grape rot, pear leaf-blight and scab, and the 

 results of other experimental work performed by field agents at 

 Greenville, South Carolina; Vineland, New Jersey; Neosho, Mis- 

 souri; Charlottesville, Virginia, and other special localities. In the 

 main, the program had to do with testing the efficacy of fungicidal 

 treatments. Each year official bulletins and circulars had been 

 issued by the Department, prepared by officials, assistants, or 

 agents of the Section (or Division as it became known in 1890) 

 of Vegetable Pathology, and, while grape diseases — black rot, 

 downy mildew, etc. — were most frequently published on, the work 

 of each year in diagnosis and treatment of fungous and other 

 classes of disease was annually summarized not only in these 

 publishing media but also in the chief's regular report made part 

 of the secretary's official report. Peach, pear, and apple diseases 

 received appropriate consideration. In 1889 circular 9 dealt with 

 "Root Rot of Cotton"; and in 1891 circular 10 elaborated results 

 of the important studies of " Treatment of Nursery Stock for Leaf 

 Blight and Powdery Mildew\" Several subjects were estimated in 

 special articles appearing in quarterly issues of the journal of 

 Mycology. Furthermore, wherever results of an especially valuable 

 piece of research were announced by officials or investigators of 

 state agricultural experiment stations, these, as far as possible, 

 were coordinated with the work of the Department. In other 

 words, a great service organization at Washington, though still 

 small in personnel and with a none too abundant annual appro-
